A multipurpose detection circuit for object detection and vehicle position determination is described. For example, the circuitry may be configured to detect foreign metal objects, living objects, and vehicles or types of vehicles above the inductive wireless power transmitter. The circuitry may also be configured to determine a location of the vehicle relative to the inductive wireless power transmitter. An example apparatus includes a measurement circuit electrically connected to a plurality of inductive and capacitive sensing circuits, including a multiplexer, for measuring one or more electrical characteristics in each of the inductive and capacitive sensing circuits according to a predetermined time multiplexing scheme. The apparatus further comprises a control and evaluation circuit for evaluating the measured electrical characteristics and determining the presence of the metal object, the living object, the vehicle or the type of vehicle, and the location of the vehicle based on changes in the measured electrical characteristics.

    描述了一种用于对象检测和车辆位置确定的多用途检测电路。例如,该电路可配置用于检测感应式无线功率发射机上方的外来金属对象、活体对象和车辆或车辆的类型。该电路还可配置用于确定车辆相对于感应式无线功率发射机的位置。一种示例性设备包括电连接到多个电感式和电容式感测电路的、包括复用器的测量电路,用于根据预定时间复用方案测量电感式和电容式感测电路中的每个中的一个或多个电气特性。该设备还包括控制和评估电路,用于评估测量的电气特性并基于测量的测量的电气特性的变化确定金属对象、活体对象、车辆的存在或车辆类型以及车辆的位置。
